I'll go straight on point.. I'm a 20 year old guy and currently studyin a college. The last year I have been feeling very... empty. I'm not sad or anything, I just don't feel anything at all. The problem is I can't motivate myself to do anything anymore. If I'm free from college, I wake up at around noon and stare at the computer screen until 4 am. Repeat next day... Things I used to love, like working out, playing guitar, football don't excite me at all anymore. I keep telling myself to stop reading useless stuff on the internet and instead be productive, like study or be creative somehow... but when I try, I do it for five minutes before I give up.

Can anyone help me out of this?
